Charge Coupled Device Signal Processing Infrared Detector Array Component.

Conventional three-phase, single-level CCD technology has been utilized to multiplex the signals from teen elements of a 0.1 eV HgCdTe photoconductive array to produce a single serial video output without degradation in the detectors signal-to-noise ratios, detectivity, or channel-to-channel isolation crosstalk. Interface circuitries between the detector elements and the CCD inputs were fabricated using monolithic bipolar ICs which had been custom designed at Texas Instruments prior to this contract for use in TIs modular FLIR systems. The clocking rates were selected to simulate first-level operation of a two-level multiplexer system operating with a 360-line parallel-scan format with 21 interlace i.e., 180 elements. Author
